Description

Technical field:

[0001] The utility model relates to a supporting and fixing structure for a dust removal filter bag, belonging to the technical field of dust removal filter bags. Background technology:

[0002] When the dust filter bag is in use, a supporting and fixing structure is generally set inside the dust filter bag. The supporting and fixing structure includes a supporting frame and fixing structures located at the upper and lower ends of the supporting frame. The supporting frame is set to prop up the dust filter bag to prevent the dust removal effect from being affected by the deflation of the dust bag; the fixing structure is set to fix the dust filter bag to prevent the dust filter bag from falling off during use and affecting the dust removal effect.

[0003] The dust filter bag in the prior art generally includes the following methods for fixing: one is to fix the dust filter bag by gluing; the other is to fix the dust filter bag by a clamp structure; the above two methods have the following disadvantages:

[0004] 1. The method of fixing the dust filter bag by gluing is very inconvenient to replace the dust filter bag. The process is relatively cumbersome, and the glue has a pungent odor. Long-term use is not good for the health of the operator.

[0005] 2. The method of fixing the dust filter bag in the form of a clamp structure, although it is easy to disassemble, its fastening effect is not good. At present, when the dust filter bag is fixed by the clamp, it is generally fixed in a single layer, and the dust filter bag is easy to loosen during use. For example, the application number is 201620335145.1, and the patent name is: Chinese authorized utility model patent for filter bag end structure and filter element composed thereof. In the above patent, the clamp structure is positioned by setting a limiting ring and a limiting protrusion to prevent the clamp structure from sliding. In the above patent, although the clamp will not move up and down, because the dust filter bag is fixed in a single layer, the friction between the dust filter bag and the joint is small. After long-term use, the dust filter bag will also slip out of the clamp, thereby affecting the subsequent dust removal effect. Summary of the invention:

[0006] The technical problem to be solved by the utility model is to provide a supporting and fixing structure for a dust removal filter bag to solve the problems faced in the industry.

[0007] In order to solve the above technical problems, the utility model is implemented through the following technical solutions: a supporting and fixing structure for dust filter bags, which is used to support and fix dust filter bags, including two fixed seat plates in a circular structure and coaxially placed, a plurality of support rods are arranged between the fixed seat plates, and an insert pressure plate seat is arranged on the fixed seat plate, and the bag opening of the dust filter bag is located between the insert pressure plate seat and the fixed seat plate.

[0008] Preferably, the fixed seat plate is in a circular ring structure, the upper surface of the fixed seat plate is provided with a top circular groove, the lower surface of the fixed seat plate is provided with a plurality of bottom anti-rotation holes, and a positioning plate is provided in the bottom anti-rotation hole.

[0009] Preferably, the insert plate seat comprises a seat plate body, a venting through hole is arranged in the middle of the seat plate body, and an inner groove in an M-shaped structure is also arranged on the seat plate body.

[0010] Preferably, a plurality of side positioning holes are provided on the inner wall of the exhaust through hole.

[0011] Preferably, a plurality of anti-slip bosses are provided on the inner wall of the inner groove.

[0012] Preferably, the positioning plate is in a U-shaped structure, and the positioning plate includes a side cylinder, and the side cylinder is inserted into the bottom anti-rotation hole. The positioning plate is also provided with an outer positioning hole, and a positioning pin is provided in the outer positioning hole.

[0013] Compared with the prior art, the utility model has the following advantages: when in use, the dust filter bag is propped up by multiple support rods to prevent the dust filter bag from being affected by the dust bag deflation during use, the bag opening of the dust filter bag is folded inward and placed in the top circular groove, and then the insertion pressure plate seat is placed on the fixed seat plate, the dust filter bag is pressed onto the fixed base through the insertion pressure plate seat, and then the fixed seat plate and the insertion pressure plate seat are connected together through the positioning plate. Through the above method, the bag opening of the dust filter bag is folded multiple times, which increases the contact surface between the bag opening and the fixed seat plate and the insertion pressure plate seat, thereby increasing the friction force, solving the problem that the existing dust filter bag is fixed by a single layer of a clamp, resulting in a small friction force between the dust filter bag and the joint and easy sliding, improving the fastening force of the dust filter bag, and at the same time solving the problem that it is not easy to replace due to gluing. The utility model has a novel structure and is easy to operate. Description of the drawings:
